Kagami no Kojou

Kokoro, a junior high student who stopped attending school due to bullying, is drawn through a full-length mirror into a castle in another dimension by a girl wearing a wolf mask. She joins six other children in a scavenger hunt organized by the mysterious girl. The goal is to find a key that unlocks a secret room, granting the finder a single wish. Participants are free to enter and exit the castle as long as they follow the rules. As the children spend time together, they form closer bonds, though the competition for the key remains a constant presence. Only one can ultimately succeed and have their wish fulfilled.
